Lunch packers avoiding sugar
If you want a sugar-free energy drink with lunch, compare the sugar information and caffeine per can rather than choosing by the front-of-pack wording alone.
Who is this for?
People counting caffeine from other drinks
A can at lunchtime adds to caffeine from coffee, tea and other sources consumed during the day.
Shoppers comparing Lucozade ranges
Lucozade describes Zero as a zero-sugar range, while it says its separate Energy range contains glucose. Check the individual drink rather than relying on the brand name.
What should you check?
Start with the exact can’s sugar information and caffeine amount, then choose a size and flavour that work for your lunch.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar and sweeteners | Read the exact sugar claim, sugars per 100 ml and ingredients. Do not treat “sugar-free” and “no added sugar” as interchangeable wording. | I want to avoid sugar, but I may also want to know which sweeteners are in the drink. |
| Caffeine per can | Compare the stated amount for the whole can, not just its volume. Red Bull lists 80 mg in 250 ml of Sugarfree; Monster Energy lists 150 mg in 500 ml of Ultra and 160 mg in 500 ml of Energy Zero Sugar. | A smaller caffeine serving matters to me more than having a larger drink with lunch. |
| Other caffeine | Add the can’s stated caffeine to what you consume from coffee, tea and other sources. The NHS advises a limit of 200 mg of caffeine a day during pregnancy. | If I have other caffeinated drinks, I need to account for those as well as the lunch can. |
| Pack size and flavour | Check whether the pack contains 250 ml or 500 ml cans and whether the stated flavour suits you. Check the caffeine label on the exact variant. | I may prefer a compact can to carry, or a larger drink to have with lunch; neither preference settles the caffeine question. |
Common buying mistakes
-
Assuming sugar-free means caffeine-free
Red Bull Sugarfree and Monster Energy’s zero-sugar drinks still contain caffeine, according to their product information.
Read the sugar information and caffeine amount separately on the exact can.
-
Choosing a larger can without checking its serving
Manufacturer figures for the examples here range from 80 mg of caffeine in a 250 ml Red Bull Sugarfree can to 150 mg or 160 mg in the named 500 ml Monster cans.
Compare caffeine per container and include other sources you consume that day.
-
Treating every zero-sugar Lucozade drink as the same choice
Lucozade distinguishes its Zero range from its glucose-containing Energy range. A range name alone does not establish the caffeine amount in an individual drink.
Check the exact product’s nutrition information and caffeine label before choosing it for a particular caffeine serving.
Relevant brand ranges

Red Bull Sugarfree is a 250 ml option for someone who prefers a smaller can.

Questions about sugar and caffeine
Do “no added sugar” and “sugar-free” mean the same thing?
No. They are different sugar claims. Read the wording on the exact drink, its sugars per 100 ml and its ingredients rather than assuming one phrase guarantees the other.
Are sugar-free energy drinks caffeine-free?
No. Red Bull states that Sugarfree contains 80 mg of caffeine per 250 ml can, while Monster Energy states 150 mg per 500 ml of Ultra and 160 mg per 500 ml of Energy Zero Sugar. Check the amount on the variant you buy.
Should I choose a 250 ml or 500 ml can for lunch?
Choose by the caffeine serving you want to account for, as well as how much you want to drink. Red Bull’s 250 ml Sugarfree can is stated at 80 mg; Monster Energy’s named 500 ml zero-sugar examples are stated at 150 mg or 160 mg. Include caffeine from your other drinks that day.
What does pregnancy guidance say about caffeine?
The NHS advises no more than 200 mg of caffeine a day during pregnancy, counting food and drinks together. A 500 ml can stated to contain 150 mg or 160 mg would account for much of that amount before other sources are included.
Is Lucozade Zero the same as Lucozade Energy?
No. Lucozade describes Zero as a zero-sugar range and says its separate Energy range contains glucose. If caffeine matters to your choice, read the label of the individual Lucozade Zero drink.
